The two things that work depend on are force and distance.
Heat depends on the temperature difference between two objects and the thermal conductivity of the materials involved.
Gravitational forces depend on the masses of the objects involved and the distance between them. The force of gravity increases with the mass of the objects and decreases with the distance between them.
Work depends on both the force applied to an object and the distance over which the force is applied. The formula to calculate work is Work = Force x Distance.
The power of a machine depends on both the force applied and the speed at which work is done. It is calculated as the product of force and speed, or the rate at which work is done.
In order for work to be done, two things must be present: force and displacement. Force is applied to an object to move it, causing it to undergo a displacement in the direction of the force. Work is calculated as the product of force and displacement in the direction of the force.
The union of two living things that depend on each other is co-dependence.

"depend" cannot be used in a simile. A simile is a comparison of two things using "like" or "as". "Depend" does not compare.
Mass and Distance
worms and straw
Mass and age.
The masses (both of them), and the distance.
Mass and distance
The masses (both of them), and the distance.
DNA And RNA
Force, distance, the angle between the two.
Interdependence means that two things depend on each other to happen.
